Letters Patent No. 109,037, dated November 8, 1870.

lmPnovi-:MENT IN PLANES.

The Schedule referred to in these Letters Patentand maldng part of the same.

To whom et may concern:

'Beit known that I, ELLIS H. MORRIS, of Salem, in the county of Columbiana and State of Ohio, have invented a new and useful Improvement in Metallic llanes, and I do declare thatt'lie following isa truc and accuratedescription thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part ot' this specilicat-ion, in which- .Figure 1 is a perspective view of my improved plane.

Figure 2 is a plan of the bottom.

Figure 3 is a'longitudinal vertical section of the dc vice.

Like letters indicate like parts in each ligure.

'lhc nature of this invention relates to an improved construction of metallic planes, whereby greater lightness and strength are secured, with ease inoperation.

The invention consists in casting thefbody of the plane with a series of intersecting ribs, covering the entire face, and in the general arrangement of its several parts, as more full y hereinafter described.

In the drawingi A.v represents a thin iron plate, cast with narrow projecting and intersecting ridges, a, on its lower face, and a rib-socket, A', on its upper surface, whichd besides giving the plane-body the necessary rigidity, receives the handle B at the rear end, secured therein by two or more bev'eLscreus, b, whose heads are countersuuk in the cavities formed by the ridge a.

The central portion of the socket forms the throat c, and in the forward part Iis 'secured a; knob, C, by which the operator guides the plane.

l) is the plane-iron,.whose slot, d, extends to the upper cud. V

'E is the cap, resting ou the upper or forward face of the iron, to which it is secured by a set-screw, F, threaded in it, passing from the rear. side of the-iron through the slot d.

G is the wedge, which secures the iron and cap in the throat in the usual manner.

wooden plane.

By extending the slot in the iron to its upper end, when I wish to remove'it for sharpening, I simply loosen the thumb-screw F, when the iron drops down through the throat. In like manner it is readjusted.

This construction of the body of the plane combines 'great strength and rjgiditywith the minimum` of weight. lhe weight ot' all metallic planes hitherto made has been the principal objection to their use,

seconded by their large costas compared with the In making such planes, after the bottom is cast it is the custom to level olf the face on an iron-planer,

4and finish on an emery-wheel--an expensive process.

Vconiignration'of the face-ridges shown, asthe same may be in curved lines, intersecting-each other to form any desired geometrical pattern.

I am well aware that cast-iron planes have been made Awith longitudinal grooves planed in their faces, and therefore disclaim the invention ot' such.

What I claim as my invention, and desire to secure by Letters Patent, is'- 1. The intersecting ridges (l onthe face of a metallic plane, as described. Y

2. The arrangement'of the handle B,knob O, planeiron D, cap E, screw F, and wedge G, with the metallic plane-body A, constructed as herein described,-

and operating as set forth. y
